ComponentOne Studio WinForms 2025 v2は、FlexPieを横に揃えたラベルで、よりきれいなビジュアルと読みやすさを向上

ComponentOne Studio WinForms by MESCIUS is a comprehensive toolkit offering over 120 advanced UI components to improve Windows Forms application development. It helps you to build visually appealing and feature-rich applications with functionalities like data visualization through charts and reports, intuitive data editing with performant grids, and modern UI elements including ribbons and docking for a user-friendly experience.

The ComponentOne Studio WinForms 2025 v2 update introduces a new data label placement option for FlexPie that aligns labels along the left and right sides of the chart to improve readability and visual structure. By moving labels out of the pie area, this option reduces overlap and congestion when working with datasets that contain many slices or small values, which are common challenges in pie chart rendering. The result is a more consistent and predictable layout that helps developers present data more clearly while maintaining a clean, modern appearance across different screen sizes and data scenarios.

ComponentOne Studio WinForms is licensed per developer on a perpetual basis and includes a 12 month subscription. Priority Support is also available. See our ComponentOne Studio WinForms licensing page for full details.

WinFormsアプリでPDF注釈を有効化

12月 19, 2025
注釈ツール内蔵のPDFビューアにより、ユーザーは元の内容を改変せずに文書をレビュー、コメント、共同作業が可能

PDF annotation in .NET WinForms PDF viewer components refers to the ability to add visual and textual markup directly onto PDF documents without altering the original content. These tools allow users to draw shapes, highlight text, insert comments, and place notes within the viewing interface, supporting workflows such as document review, feedback, and approval. This functionality improves collaboration and clarity in document handling, making it well-suited for document processing tasks in WinForms applications.

Common features include:

  • Freehand Draw (Ink Annotation) allows users to sketch, underline, or handwrite directly on the page using a mouse, stylus, or touch input, making it ideal for markups and signatures.
  • Lines provide a simple way to connect points or emphasize linear elements within a document, often with configurable thickness, color, and opacity.
  • Rectangles enable users to highlight or frame areas of interest, supporting both outlined and filled styles for visual emphasis.
  • Ellipses offer a similar highlighting function to rectangles but with a rounded shape, useful for circling content or marking irregular regions.
  • Arrows are commonly used to direct attention to specific content, combining line styling with arrowheads to clearly indicate focus or flow.
  • Sticky Note annotations allow users to attach comments to precise locations in the document, typically displayed as icons that reveal text on interaction.
  • Free Text enables direct placement of typed text onto the page with control over font, size, color, and alignment, supporting clear, visible commentary without pop-ups.

ComponentOne Studio Enterprise 2025 v2は、高性能な輪郭マッピングとグラデーション可視化機能でWPFアプリを強化

ComponentOne Studio Enterprise is a comprehensive suite of .NET UI controls developed by MESCIUS (formerly GrapeCity) designed for building rich, interactive desktop, web, and mobile applications. It provides developers with a broad range of tools and components-including data grids, charts, reports, input controls, and advanced data visualization features-for platforms such as WinForms, WPF, ASP.NET Core, Blazor, WinUI, and .NET MAUI. The suite emphasizes performance, flexibility, and ease of integration, helping teams create consistent, feature-rich user experiences across multiple application types while maintaining a unified development approach.

The ComponentOne Studio Enterprise 2025 v2 update introduces 2D Contour Charts in FlexChart for WPF, allowing developers to represent three-dimensional data on a two-dimensional surface through contour lines or shaded bands that highlight areas of equal value. This capability delivers a clear visual understanding of gradients, surface characteristics, and other continuous data patterns. With support for multiple contour types, customizable contour levels, and flexible gradient color palettes, developers gain precise control over how value transitions are presented. These enhancements make the WPF contour chart well suited for scientific and engineering analysis, elevation and surface mapping, and any application that requires accurate comparison of value distribution across two variables.

専用のダイアログでレポート入力を最適化

ダイアログパラメータフォームによる整然かつ一貫性のあるレポート作成と、フィルター・グルーピング・計算に必要な正確で検証済みの入力を確保

Dialog forms for parameters in reporting provide a structured and user friendly way to collect the inputs needed for accurate, relevant reports. Instead of relying on manual entry or remembered criteria, users are guided through fields that ensure consistent and valid information. This improves report quality and reduces errors in scenarios such as choosing date ranges, product categories, regions, or departments. By centralizing parameter entry in a clean interface, dialog forms let users focus on interpreting results rather than managing input details.

Several .NET WinForms reporting components allow you to create dialog forms for parameters, including:

  • DevExpress Reporting lets you create guided parameter dialogs that collect accurate user inputs, improving report precision, usability, and efficiency across applications.
  • Telerik Reporting allows you to build intuitive parameter dialogs that improve data selection, ensuring users generate consistent, reliable reports with minimal effort.
  • FastReport .NET WinForms facilitates customizable parameter dialogs that validate user input, enhancing report accuracy and simplifying complex filtering and configuration tasks.
  • Stimulsoft Reports.NET enables structured parameter dialog creation that helps users supply correct reporting criteria, delivering clearer insights and more dependable results.
